Description

Technical Field

[0001] This utility model belongs to the field of vibration monitoring technology, and in particular relates to a solar-powered vibration monitoring device. Background Technology

[0002] Steel towers and chimneys in the petrochemical industry, as well as wind turbine towers in the wind power industry, are typical tall structures. These structures are characterized by high flexibility and are easily affected by wind loads, resulting in wind-induced vibrations. With the development of the social economy and the continuous advancement of design and construction methods for tall structures, these structures have larger height-to-diameter ratios and are more significantly affected by wind loads. When the structure resonates under wind loads, the vibration amplitude is huge, affecting the safety of the tall structure. At the same time, the vibration of the structure can lead to stress concentration at the bottom or weak points of the structure, causing fatigue, damage, or even fracture. Therefore, it is necessary to conduct long-term vibration monitoring of tall equipment and conduct safety assessments based on the data. This is of great significance for ensuring the safety of tall structures.

[0003] A vibration monitoring device is an instrument used for high-precision monitoring of the vibration of critical equipment. It can be directly installed at locations on the main structure where significant vibration occurs; for tall structures, it is typically installed at the top. The device incorporates high-precision sensors to collect data such as vibration acceleration and tilt angle, and transmits this data to a terminal via IoT card technology. As the primary monitoring component, the vibration monitoring device needs to provide stable, long-term data monitoring and transmission. However, the environment at the top of tall structures is often harsh, making the device susceptible to the effects of rain, strong winds, snow, and other natural environmental factors. Furthermore, ensuring a continuous power supply for the device is a critical issue that needs to be addressed. Utility Model Content
